Value null of type org.json.JSONObject$1 cannot be converted to JSONObject
I am using the AsyncTask
My MainActivity is here
public class MainActivity extends AppCompatActivity {
String data ;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
DownloadWeatherData downloadWeatherData = new DownloadWeatherData();
try {
downloadWeatherData.execute("http://samples.openweathermap.org/data/2.5/weather?q=London,uk&appid=b1b15e88fa797225412429c1c50c122a1").get();

String weatherdata;
#Override
protected String doInBackground(String... urls)
{
try {
URL url = new URL(urls[0]);
HttpURLConnection connection =(HttpURLConnection) url.openConnection();
connection.connect();
InputStreamReader inputStreamReader = new InputStreamReader(connection.getInputStream());
int data = inputStreamReader.read();
while(data!=-1)
{
char str = (char)data;
weatherdata+=str;
data = inputStreamReader.read();
}
return weatherdata;
}
catch (MalformedURLException e)
{
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
#Override

super.onPostExecute(s);
try {
JSONObject jsonObject = new JSONObject(s);
String info = jsonObject.getString("weather");
Log.d("weatherpart",info);
} catch (JSONException e) {
e.printStackTrace();
}
}
}

You are doing it wrong. Weather is an array not a json object. Do it like this:
JSONObject jsonObj = new JSONObject(s);
JSONArray ja_data = jsonObj.getJSONArray("weather");
int length = ja_data.length();
for(int i=0; i<length; i++) {
JSONObject jsonObj = ja_data.getJSONObject(i);
.
